Cactus Wren: Resident of arid and semi-arid regions in the southwestern United States, including southern California, Nevada, Arizona, New Mexico, and western Texas, extending south to central Mexico. Preferred habitats include deserts dominated by cholla cacti and other succulent cacti, spiny trees, and shrubs, with high temperatures, low humidity, and scarce water.

Breeding and Nesting

Cactus Wren: Two to seven pink eggs, flecked with brown, are laid in a nest made of rootlets, grass, and various stems, lined with feathers, hair and fur, and built in a rock ridge, crevice, burrow, bank, or building. Incubation ranges from 12 to 14 days and is carried out by the female.

Foraging and Feeding

Cactus Wren: Eats insects, including ants, beetles, grasshoppers, and wasps; occasionally takes seeds and fruits. Forages by searching under leaves and ground litter; also hunts in bushes and trees.

Vocalization

Cactus Wren: Song is a quick low guttural "guah guah guah guah guah", gaining in speed toward the end. Call consists of a rapid buzz of varying intensity.
